Perhaps you should try some spelling variations:
luan trong » quan trong, luat trong, luan tuong
tang luan » dung luan
thanh lap » thanh san, phan lap, thanh hai
anh tang » anh bang, anh dang, anh nang
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh cac, than cua
chu han » chu van

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu xanh) OR (chu han)) - anh tang luan trong cong dan ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) or (chu han)) - anh tang luan trong cong dan ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) or (chu han)) - anh tang luan trong cong dan ((than cap) OR (thanh lap))*.
